Here’s a combo for you: dance act du jour Disclosure, disco icon/go-to musicianNile Rodgers, “La La La” vocalist Sam Smith and songwriter Jimmy Napes put their heads together for the old-school slab of ’80s funk that is “Together.” The new track hits some interesting highs, but unfortunately doesn’t go far enough, in that its run time is less than two-and-a-half minutes. It’s a bit of a short-change moment for the listener, especially given the combined talent involved.
